ABSTRACT

This study aims to explore the relationship between inter-brain synchronization and decision-making behavior during dyadic risky decision-making, so as to provide theoretical support for the systematic research on the neural mechanism of dyadic risky decision-making and enrich the research system of interpersonal interactive decision-making in the field of social cognitive neuroscience. Based on brain-to-brain coupling, this study adopts hyperscanning technique with functional magnetic resonance imaging, electroencephalography, functional near-infrared spectroscopy and other devices to simultaneously record the interaction and brain activities of two subjects in the scenario of dyadic interactive risky decision-making, and collect and analyze the brain signals during the decision-making process. The results clarify the correlation between inter-brain synchronization and decision-making behavior in dyadic risky decision-making, which provides theoretical support for relevant research and enriches the research system of interpersonal interactive decision-making. The innovation of this paper lies in that it investigates dyadic risky decision-making from the perspective of inter-brain synchronization using hyperscanning technique, which provides a new perspective for understanding the cognitive mechanism in such decision-making process and fills part of the gaps in empirical research on the neural mechanism of interpersonal interactive decision-making in the field of social cognitive neuroscience.
